ABSTRACT: Hundreds of kilometres of unpaved roads are built each year by the Canadian forest industry to provide access to harvest sites. These roads are encountering reductions in bearing capacity and increasingly frequent access interruptions due to excess water in roadbeds combined with climate change and suboptimal construction, management, and maintenance practices. FPInnovations, in collaboration with TenCate Geosynthetics, Presto Geosystems, and Blue Ridge Lumber Inc., is conducting a comprehensive field study aimed at selecting 4 technologies (i.e., moisture wicking and/or high strength woven geotextiles, perforated geocells, and corduroy) and evaluating their ability to improve road strength. This paper describes the testing and site instrumentation (moisture, temperature, and soil pressure sensors). It also discusses preliminary results from performance evaluation (visual characterization, sensor data) of test sections as a comparison to a reference.
RÉSUMÉ: Des centaines de kilomètres de chaussées non revêtues sont construits chaque année par l’industrie forestière canadienne pour permettre l’accès aux ressources. Ces routes sont confrontées à des réductions de capacité portante et à des interruptions d’accès de plus en plus fréquentes en raison de l’excès d’eau dans la structure, combinées aux changements climatiques et aux pratiques de construction, de gestion et d’entretien non-optimales. FPInnovations, en collaboration avec TenCate Geosynthetics, Presto Geosystems et Blue Ridge Lumber Inc., mène une étude de terrain visant à sélectionner 4 technologies (c.-à-d. geotextile drainant et/ou à haute résistance, géocellule perforée, corduroy) et à évaluer leur habilité à améliorer la capacité portante de ces routes. Cet article décrit les essais terrain, sur un site instrumenté avec des capteurs de teneur en eau, des thermistances et des capteurs de pression du sol. Il traite également des résultats préliminaires d’évaluation de la performance (caractérisation visuelle, instrumentation) de chaque section d’essai en comparaison à la section référence.
